[CU2] funny noise from the engine when slow accelerate

[tron07]

The fuel is from dealer as my car only few days old. I think the dealer wont put anything other than 98 ron....

they can be a cheap ass and put in cheap fuel... quickly fill with 98 to bring the octane level up

OK got the car back and its NOT doing it anymore...unsure what the hell they did but its not doing it. The sheet says "rattle noise may be cause by not using premium fuel. Vehicle should only use premium unleaded. Road Test Vehicle - ALL OK".

Well time will tell wether it comes back, but its had two tanks of 98 in it now, and yes I argued with the "tech" and he said if it continues bring it back and they might have to take some timing out of it...bit of a worry, why don't I just retard it a bit myself then...stuff the V-tec and the computers, out comes the timing light and the socket set...

Anyway, getting tint done Friday in a darkish colour...maybe that will make the car feel better..lol

Can't do that because the Euro doesn't have a distributor...

Make sure you tell them to take the parcel tray out! Don't forget......

Twas a joke...sorry need to use the LOL and etc

You can still adjust the timing though...

All good.
Can you adjust the timing? Ignition timing has to be changed through the ECU, so maybe by using an interceptor box?

Good for you mate!! Now, its my turn to get that solve.
For your window tint, like what typeR said...get them to tint the whole rear screen.
I have some pictures in my previous post for your reference.
Thanks!

Might have a dud knock sensor. Given the higher compression ratio of the CU2, having a fully functioning knock sensor is very important.

Sent my car for service today. They told me they reset all the system and tuned the car again to remove the noise. They also told me they check again and again carefully....HOWEVER, 5 minutes after i took my car, the noise came back!!!! Although not as obvious as before, but it still there.
I will call them tomorrow to give them the shit! Dont know what else i can do

Get them to reset everything again and maybe flush the fuel system inlcuding replacing the fuel filter, thats my only suggestion. To me it sounds like gear box and NOT engine. Like in an old Diahatsu Charage Auto under light acceleration you get the noise through the torque converter??

got the car tinted and the guy did the whole rear screen, he has done a few of my cars to date. I went with 3m darkest legal cause its a lease, I did have my eye on the 20% film though which I should have done for the rear due to the gay light coloured parcel shelf.

so i guess your car is ok now. No more funny sound at all??
I agreed with you...its not the fuel.
Just hope that they will solve my problem soon.

OK it was all good for a while however its back, and its back just before a change up in gear and just after. Its definitely gear box and not engine, it definitely sounds like torque converter and not "pinging or rattle due to not using premium fuel". I am about a pffteenth from a letter to Honda Australia especially after the disorganised and stupid service people who booked my car in today but actually did not, then did not order the parts cause they cannot get them and thus I believe they have removed them from another vehicle ready for delivery...rather bad in my books, good up until you get the car then its been downhill since...seems I just got my questionnaire in the post today...time to let my mind loose...

So how did you go Eur001???
